汽车化油器真空省油器作用时间应符合技术要求,若过早、过晚打开都影响汽车的性能。过早,造成燃油超耗;过晚,造成局部区域混合气过稀,汽车过渡加速性不好。所以要求真空省油器要在一定的真空度作用下开启。目前国内多数厂家在无综合流量试验台的情况下,其检测方法都是分开进行的。我们厂对231S_c型化油器的真空试验,原是由电源、电路及真空活塞在真空度作用 Car carburetor vacuum fuel pump time should meet the technical requirements, if too early, too late to open the car will affect the performance. Premature, resulting in excessive fuel consumption; too late, resulting in the local area of ​​the mixture is too thin, the transition acceleration of the car is not good. So ask the vacuum fuel pump to open under the action of a certain degree of vacuum. At present, the majority of domestic manufacturers in the absence of integrated flow test bench, the test methods are carried out separately. Our factory on the 231S_c carburetor vacuum test, originally from the power supply, vacuum circuit and vacuum piston role
